utensils of pumpkin or squash plants.
Duba’a is a kind of pumpkin or squash plant. Before islam people were using utensils (hollow pots/jars) made from pumpkin or squash plants for preparing alcoholic drinks. these utensils were named Ad-Dubba, Al Hantam, Al Muqaiyar, or Al Muzaff. With the arrival of islam wine was forbidden and people were not even allowed to keep or preserve nonalcoholic drinks in such pots, because after a while the nonalcoholic drinks would start to ferment and convert into alcoholic drinks.
The term is not mentioned in the Holy Qur'an.
Anas bin malik said Allah’s apostle said: “do not make drinks in Ad-Dubba nor in Al Muzaff at.” abu huraira used to add to them Al Hantam and An-Naqir. [Shahih Al Bukhari, the book of drinks.]
